Sigh. Just won't fucking let it go will you? Either the chloroplasts have dried out and exploded from the heat or they haven't. He removed the source of the heat so unless he has super low humidity, spraying the leaves isn't going to magically rehydrate them. The simple process of transpiration will move water to the leaves and out through the stomata. So in this instance, having low humidity (and thus a higher DIF at the leaf surface) would speed up the process of water movement through the leaf. What this means is that when you are burning your leaves the plant is moving water to the leaves as fast as possible, and it just can't keep up and the leave gets damaged. Yes, spraying the leaves at the very moment that you realize they are burning would help by increasing humidity at the leave surface and lower transpiration and water movement loads but after 20 or so minutes after moving the light, the plant will be able to transpire and cool the leaves.

So there, that is the long answer. You should never be burning leaves unless you run out of grow room height. If you put HID lamPs too close they put out more lux than the sun. Blasting your plants with 150,000 lux doesn't grow big buds, it bleaches leaves and dries out the oils....the oils that get you high an make weed smell good. 40k lux for optimum veg and 60-80k for flower.

there we go, thats a better explanation. i didnt mean itd "magically rehydrate them" but rather hydrating the chloroplast and stop from any further withering if treated, the sooner you do it the better but you could leave it, wont kill them.
imo, outdoor beats the shit out of any hid, why use energy when you can run them under the sun, use my balcony for my females and inconspicuous bushes for males i want to breed, or shorter females. havent touched an hps for years but im afraid this year im gonna need to, cant wait till september unfortunately.
